Trying to avoid "extreme or sustained harassment" is in it's mission something much more narrow than clearing a place until it's "positive".

While I could agree with "We all become better people when we can share our own perspectives and hear the perspectives of others, especially when they are different from our own.", I don't think that the overemphasis on perspectives makes it a particular trustworthy statement. It feels like it's a preparation for the demand of a relativist language. A conversation where everyone feels right, even if they aren't. Which appears to me to be some kind of a no-grow area.
